Crashed
in the bush on the north shore of Lake Superior, 3 miles north of
Rossport, Ontario.

While en route engine RPM increased over the
danger mark, which was followed by a rapid loss of height and forward
speed and an emergency forced landing was made on a high ridge of rock
on hills north of Rossport.

The damage to aircraft was listed as "substantial", and the
Seabee was never repaired or rebuilt.

Pilot John William Donaldson, who was the sole occupant, escaped with
"minor" injuries.

The cause of the accident was suspected of being the propeller finding
its way into neutral position. This may have been due to reversed
pitch control becoming unlocked and permitting the propeller to go into
neutral position, something which could not be controlled by the
propeller control inside the aircraft.

Carburetor icing was also suggested as possible cause of accident, as
when aircraft was visited, there was no evidence of the pitch of the
propeller having gone into the neutral position.

Superior Airways said at the time that it was stripping
the aircraft of the doors, instruments, seats, gas tank, flaps
& ailerons, tail planes and other material. The wings and fuselage
were left in the bush. (Information from Terry Judge 2009-04-23)

It seems that the fuselage was transported to Thunder Bay for outside
storage, while wings were stored at Vickers Height, a few miles outside
Thunder Bay.
